Good to know

Six things about the centipede

Legs

Not a hundred legs

A brown centipede has 15 pairs of legs: 30 in all. No centipede has exactly 100.

Hunter

A speedy hunter

Centipedes are hunters. They run down woodlice, spiders and insects, mostly at night.

Claws

Poison claws

Just behind the head is a pair of claws that inject venom into its prey. They are too weak to hurt a person.

Tell

Centipede or millipede?

A centipede has one pair of legs on each segment, sticking out sideways. A millipede has two pairs, tucked underneath.

Growing

Growing more legs

Young brown centipedes hatch with only seven pairs of legs and add more each time they shed their skin.

Flat

Flat for a reason

Its flat body lets it slip into narrow cracks under bark and stones.

How to spot one

Lift a stone or a log and watch for a fast, flat, orange-brown animal racing for cover. It will be gone in a second or two.

Lend a hand

How to help

Leave stones, logs and leaf litter in place. Centipedes hunt many of the small animals gardeners call pests.
